When riding the subway, it’s not uncommon to see signs warning travelers of route changes and to be wary of pickpockets; however, According to the UK’s Daily Mail, London’s Farringdon Station has an uncommon warning for tube users:

“The mice at this station have been attacking customers. Please place the bottom of your trousers into your socks to avoid being a victim of the Farringdon mice.”

Apparently, mice have been “attacking” the feet of commuters as they wait for their train. It’s a bit of a mystery, however, as tube staff deny being the ones to put the sign up. While it’s now been taken down, thousands of people have already seen it and have taken to Twitter to spread the word.

For example, @alfredcamp wrote, “The #EssexLion turned out to be a harmless pussycat. The #FarringdonMice turned out to be far more sinister!”

@AlexKammAndSons also tweeted, saying, “I am not passing through Farringdon without a packet of mini cheddars as mouse bait #Farringdonmice.”

And @secret_escapes is now having nightmares. “Last night I dreamt that I was savaged by a (very large & scary) mouse. Now this warning appears. OMEN. #FarringdonMice”

And you thought having to sit next to the screaming child was bad. On a Kenya Airways flight from Amsterdam to Tanzania, a Swedish woman named Lena Pettersson was forced to sit near a corpse.

When she sat in her seat, Pettersson noticed a man on the other side of the aisle having seizures and sweating. Moments after the flight took off, he was dead. The cabin crew laid the body over three seats and covered the deceased with a blanket, although his legs were left sticking out. The woman was then forced to sit next to the corpse for the remainder of the flight.

Ms. Pettersson commented, “Of course it was unpleasant, but I am not a person who makes a fuss.”

After issuing a complaint, the airline refunded her half the price of her ticket, $500.
